Most common are destructive tests, such as stress, fatigue and micro sectioning tests. There are also methods that allow non-destructive testing (NDT), so the material can be still be used after testing. Common methods are ultrasonic, X-ray, HF Eddy Current, Radio Wave testing or thermography.

An equation relating the length that you measure l to the ship's proper length l0  is  

l =l0/y. This is further explained below.

<h3>What is an equation relating the length that you measure l to the ship's proper length l0?</h3>

Generally, Any object's length in a moving frame will look shortened or contracted when seen in that direction. The Lorentz transformation may be used to determine the amount of contraction.

In conclusion, To use the Lorentz Lorentz transformation, the length Lo-x2 - may be determined if it is measured in the moving reference frame. Hence the Resultant l = l0/y.

395,000 meters in 9000
marta [7]

Answer:

43.88 meters per second

Explanation:

The computation of the speed is shown below:

As we know that

Speed = \frac{Distance}{time}

where,

Distance is 395,000 meters

Time is 9,000 seconds

Now placing these values to the formula

So, the speed is

= \frac{395,000}{9,000}

= 43.88 meters per second

As speed shows the relation between the distance and time and the same is to be considered i.e by applying the formula

How are air temperature and air pressure related?
geniusboy [140]

Answer: Whenever the temperature is high, the air pressure is low.

Explanation:As the temperature rises, the air gets heated, expands, and becomes lighter. … As a result, the air pressure in such areas decreases.
